Q: The half-life of a first-order reaction is independent of which parameter?
Solution:
The half-life of a first-order reaction is independent of the initial concentration.
Steps: 6
Show Steps
Step 1: Understand what a first-order reaction is. It is a type of chemical reaction where the rate depends on the concentration of one reactant.
Step 2: Learn about half-life. Half-life is the time it takes for half of the reactant to be used up in a reaction.
Step 3: Recognize that in first-order reactions, the half-life is a constant value. This means it does not change over time.
Step 4: Identify the parameters that can affect a reaction, such as temperature, pressure, and initial concentration.
Step 5: Focus on the initial concentration. For first-order reactions, the half-life does not depend on how much of the reactant you start with.
Step 6: Conclude that the half-life of a first-order reaction is independent of the initial concentration.
